希瓦氏菌生物被膜研究进展

希瓦氏菌（Shewanella spp.）是海产品中常见的优势腐败菌，易在食品加工设备表面形成生物被膜而难以清除。生物被膜的存在不仅会造成食品的持续污染和交叉污染，也会影响加工设备的使用，从而对国民健康和经济发展造成威胁。目前，针对希瓦氏菌生物被膜的研究主要集中在表型研究上，对其生物被膜形成分子机制的研究尚处于起步阶段。总结希瓦氏菌生物被膜的形成过程，重点论述希瓦氏菌生物被膜的形成机制并对希瓦氏菌生物被膜控制方法进行简要概括，展望未来的研究方向，以期为希瓦氏菌生物被膜的深入研究提供参考。

Advances in Shewanella spp. Biofilm

Shewanella spp. is common specific spoilage dominant microbe in seafood, which easily forms biofilm on the surface of food processing equipment and it is difficult to remove. The existence of biofilm will not only cause the continuous contamination and cross-contamination of food, but also can affect the use of processing equipment, thereby threaten the national health and economic development. At present, studies on the biofilm of Shewanella spp. mainly focus on the phenotype research, and the molecular mechanism of biofilm formation is still in its starting stage. This paper summarized the formation process of Shewanella spp. biofilm, focusing on discussion of the formation mechanism of Shewanella spp. biofilm, briefly introduced the controlling method of the biofilm, so as to provide theoretical basis for intensive study of biofilm of Shewanella spp. and prospected the study direction in the future.
